Abstract: Lightwaves (1), which carry data signals and beacon light, are used for establishing a connection between a receiver and a transmitter located remote from the former. An acquisition sensor (171) is provided for acquiring the lightwaves (1) in the receiver, which generates acquisition sensor signals (Sc) from the receives lightwaves. The lightwaves (1), which are conducted over a telescope (2) and a beam splitter (R4), are fed to the acquisition sensor (171) as well as to a scanning device (5). Besides useful signals (Sa, Sb), an additional signal (Sw, Sm', Sm) is obtained with the aid of the scanning device (5), which is used for making the acquisition easier.

Abstract: A street sweeper comprises a vehicle mounted on ground wheels for running along a roadway with a two part pivotal boom arrangement carried on the vehicle and pivotal upwardly, downwardly, forwardly and rearwardly together with outwardly to respective sides. At the end of the boom is mounted a brush member which is suspended on the boom from the top of the housing with ground wheels at the front and rear of the housing so that the housing can rollover the ground.  The housing carries a transverse cylindrical brush member rotating about an axis transverse to the housing and thus at right angles to the length of the boom.  The housing floats by slots on a pin at the end of the boom so that its height is controlled by the ground wheels but its position and the orientation of the rotary axis of the brush is controlled by the position of the pin at the end of the boom. The brush member can thus be moved readily to required locations for a brushing action to sweep materials forwardly or rearwardly onto a roadway for collection by a conventional street sweeper.

Granted: 2004-02-10
Abstract: In a fire pumper truck, the vacuum priming system only primes the truck pump. In this invention, using piping provided, the one-way vacuum priming system is connected to a three-way selection valve; the second outlet is connected to the pump on the truck while the third outlet is connected to the valve which supplies outside water. The selection valve thus allows the priming command to be directed to the pump on the truck or to a semi-rigid, large diameter suction pipe connected to the valve which supplies outside water while the reserves in the truck are pumped. The invention thus avoids firefighting being halted in order for the truck's pump to be primed when the water supply source is changed.

Abstract: Cette invention concerne une approche de traitement pour la polymérisation in situ rapide et efficace de mélanges précurseurs spécialement préparés en vue de produire la production près de la côte désirée d'objets/articles aux dimensions exactes. Cette approche se base sur l'utilisation de compositions polymérisables constituées par un mélange d'un plastifiant réactif et d'un initiateur, renfermant éventuellement aussi un polymère mort, ces compositions étant du type semi-solide et n'entraînant qu'un faible rétrécissement lors du durcissement, étant donné leur nature partiellement polymérisée avant le traitement. Les articles ainsi produits présentent une surface et une noyau intérieur, la composition du matériau de surface étant distincte de la composition du matériau du noyau, tandis que la surface et le noyau forment une unité solidaire monobloc. Ces articles sont en outre stables en dimensions et permettent une réplication haute fidélité.

Title: Systemes et procedes permettant une egalisation passive de la pression dans des transducteurs acoustiques
Inventor: FLOOR JAMES W
IPC: H04R7/04
Filed: 2000-03-10
Granted: 2009-10-06
Abstract: Ces systèmes et les procédés correspondant permettent d'égaliser la pression entre une cavité intérieure et un environnement intérieur et ce, dans ladite cavité intérieure, tout en assurant une isolation acoustique entre les deux environnements, de sorte que l'énergie acoustique se propageant dans un environnement n'entraîne pas de vibrations dans l'autre. Dans une réalisation, on utilise ces systèmes d'égalisation de pression pour égaliser la pression des deux côtés d'un projecteur à bobine mobile, ce qui réduit les effets préjudiciables qu'une différence de pression sur le projecteur à bobine mobile peut avoir sur le fonctionnement de celui-ci et diminue les risques que la propagation de l'énergie acoustique n'entraîne une annulation de phase susceptible d'influer sur les bonnes conditions de fonctionnement du projecteur à bobine mobile.

Abstract: La présente invention concerne un procédé de traitement de fichier, un dispositif informatique et un support mémoire. En l'occurrence, on commence par segmenter un fichier de façon à éviter les irrégularités de distribution des données dans le fichier. Pour chaque segment, on recherche une fréquence d'occurrence d'un caractère de façon à déterminer un paramètre de compression. Dans chaque segment, on réalise une compression des données en fonction des différents paramètres de compression. Ainsi, ce seront des données comprimées qui seront enregistrées si la compression est effective, ou des données non comprimées si la compression n'est pas effective. En outre, on enregistre simultanément une information permettant de savoir dans quel mode de compression chaque segment considéré est enregistré.

Filed: 2001-01-24
Granted: 2009-11-03
Abstract: This invention provides an actuation system for a highly underactuated gripping mechanism with ten degrees of freedom, which requires only two actuators, one for actuating the opening and closing of three fingers and the other for the orientation of two rotatable fingers with synchronization. Underactuation between the fingers is provided by a one-input/three-output differential which is associated with an orientation mechanism so that an orientation-fixed finger is deactivated when the two orientatable fingers are rotated to face each other for a pinch grasp.  Each finger is enabled to be self-locked in its closing and opening action when the power is off. In one embodiment of the invention, a planetary gearing system is used for the differential. In another embodiment, a Geneva mechanism is used for the orientation transmission, and a fastening interface using an indexing ring is provided to connect an external driving apparatus.
